'Specification of Letters Patent. Patented Sept. 28, 1920.

Application filed July 5, 1919. Serial No. 308,815.

T 0 all to 7mm it may concern:

Be it known that I, HARVEY B. Rnrrn'r'ro, a citizen of the United States. of America, and resident of \Vheeling, county of Ohio, and State of lVest Virginia, have invented certain new and useful Improvements in Flexible Connections for Stoves and the like, of which the following is a'specification.

This invention relates broadly to tube connections of the character commonly employed in connecting oil and gas stoves or burners to a fount or other source of fuel supply.

The primary object of the invention is to provide a tube connection for oil and gas stoves and the like, which may be readily bent int-o any shape required or made necessary by the relative positions occupied by the stove or burner and the supply fount or pipe with which connection is to be made.

A further important'object is to provide,

in association with a connecting tube composed of lead or other like soft and flexible metal, a pipe fitting or coupling by means of which a tight and leak-proof joint may be readily formed between said. tube and the supply fount or pipe.

A still further object is to provide, in a device of the character mentioned means whereby the belled coupling end of the soft metal tube is reinforced to resist the drawing force applied thereto in effecting the formation of a tight joint.

In describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a side elevation of the invention; and v I Fig. 2 is an enlarged longitudinal section of the same.

Referring to said drawings, 1 designates a tube composed of lead or other like soft and flexible metal, which is. adapted to be readily bent by hand into any form appropriate for connecting a stove, burner, or the like, to a supply fount or pipe, as when the parts to be connected are located in nonalined relation. One end-of said tube, preferably that end which connects to the stove or burner, has fixed thereon in a suitable manner, as by soldering, an exteriorly threaded nipple 2 adapted for firmly atto the outlet of an oil fount.

taching said end to a tubular fuel-conducting portion of such stove or burner.

The opposite end of the tube 1 is flared outward to form a bell 3 adapted for the reception of the rounded end or nose of one end of a nipple 4 which has its opposite end threaded for attachment to a supply pipe or A coupling sleeve 5 has an internal flange 5 at its inner end disposed in loosely embracing relation to the tube 1 behind the bell 3 of the latter and is screw-threaded interiorly from its outer end throughout asuitable distance to adapt it for threading over the adjacent end of said nipple A. As is obvious, said sleeve 5 acts to draw said nipple and said tube together as it is tightened upon the nipple, causing the nose of the latter to firmly seat within the bell 3.

To reinforce the bell 3 and to obviate the injury which would otherwise result thereto from wear and from the biting, pinching and bruising pressure exerted through the flange 5 against the soft metal of the bell, a band 6 of a relatively harder metal is rigidly mounted, as by soldering, in embracing relation to the tube on which said bell is formed, said band being flared at its outer end to correspond with the flare of the bell and to seat against the latter, as shown in Fig. 2. The flared end of the band receives the flange 5 of the coupling sleeve 5 thereagainst and, consequently, protects the'bell from the injury mentioned.

As is manifest, the invention provides a coupling device which may be conveniently applied by unskilled persons without the assistance of a plumber.

What is claimed is- V 1. As a new article of manufacture, a flexible metal tube connection for stoves and the like, comprising a soft-metal tube having one end flared to form a bell, a band of relatively harder metal rigidly carried in embracing relation to said end of said tube behind said bell and having its outer end shaped to form a shoulder which conformably seats against said bell for reinforcing the latter, a nipple having one end adapted for seating against the interior face of said bell and carrying screw threads, and a coupling sleeve slidably mounted on said reinforced end and having an internal flange said nipple.

adapted for assuming seated relation to the 1 shoulder of said band, said sleeve also having threads for engagement with those of Z'Asa new'article of manufacture, a flexibletube connectlon for stoves and the like, comprising a tube composed of readily bendable metal, oneend of said tube being provided With suitable attaching means and the otherend thereof having a bell formed therein, a band of a relatively hardermetal rigidly carried in embracing relation to the belled end of said tube and having an end provided With a shoulder against Whichthe back of said bell rests, a nipple having a 7 rounded male 'end' adapted for seating against the internal face of said bell and carrying screw threads at its OPPOSltQ end,

and a sleeve slidably mounted on saiidb'and and having an internal flangeat its inner end-for seating against said shoulder, said sleeve relative adjustment.

In testimony whereof I affix my'signature in presence of two subseribing Witnesses.
